Motivation

Electricity Shortage is knocking our doors

In Taiwan, insufficient electricity supply is always an important issue. Especially in summer, we are usually under the risk of power outage. Sometimes, it really happened(8/17 Power Outage in Taiwan)In both Trends of Demand and Stability imply electricity shortage will be an even serious problem.

Electricity demand is ascending

In the past 4 years, the demand of electricity in Taiwan has increased about 8%. Furthermore, our government intends to shut down all the nuclear power plants by 2025. In fact, nuclear power plants account for 14% of total electricity supply.

Electricity supply becomes unstable

Operating reserve rate keeps decreasing and it hasn’t achieved the goal set by Taipower corp. 4 years in a row. Low operating reserve rate implies any unexpected power plant shut down Taiwan will suffer from power outage.

Current policies are paved with good intentions but inefficient

Although the government enforce a bunch of different policies to solve this problem, it isn’t effective at all. For example Save the electricity on your own, Countrywide Electricity saving completion. However, governors didn’t clarify the reasons of wasting electricity for different regions. Without comprehending the actual reasons of wasting electricity, how can they come up with an appropriate policy to curb the electricity waste.

Our goal

The Electricity saving policies enforcing process can be broken down into 3 parts, Identify the regions wasting electricity, figure out the reasons they wasting, and Set up corresponding policies. Our product was designed to shorten the time consumed during this process and help governors apply the right policies on the right regions.

How we achieve our goal? U-Optimizer

To customize the policies by region is the key of achieving our goal. We utilized a lot of open data, Including demographics data, economic data, electricity usage data ….etc. Besides, we use both supervised and unsupervised machine learning methodologies to cluster the villages around Taiwan. In the end, we want to deliver a system which can assist governors to arrange the current policies to appropriate villages or set up a whole new policy for specific villages.

Outcome

Cluster1 : Multi Resident Housing

很明顯的教育程度是大學以下比例跟六人一宅戶數比例相當高,像是有名的一戶百口人的洲美里就在這一群中,這群的戶均用電最低,可能是一戶多人所以拉低了戶均用量,偏向outlier的型態

Cluster2 : Disadventaged Family

其實大部分指標跟總中位數很接近,但可以發現在教育程度是大學以下比例偏高,而房價中位數偏低,所以我們認為是狀況偏向些為弱勢家庭,位置也是在台北市中心偏外圍的地區。

Cluster3 :General Family

各項指標皆與總體中位數差不多的,故命名為大多數的一般家庭,以台北市而言應該是像小家庭的結構

Cluster4 :Three Generations Family

教育程度是大學以下比例最低,老年人口比例偏高,而扶養比最高,可猜測也有小孩,房價中位數也是最高,因此可能是偏市中心的小康家庭,這是用電量是屬於偏高的族群

Cluster5 :Single Group

這一群的單身率最高,由較高的老人人口比例可以看出,可能有跟父母同住,而用電量是屬於偏高的族群
